62’ Cub Mechanical Resto

Postby Zack11122 » Wed Jul 07, 2021 7:42 pm

I figured I’d start something to keep track of the mechanical restoration of my 62’ cub.

62 cub


I bought it from its original own a few weeks back. The machine came with the original manuals that he received when purchased new. So first things first is the right side brake was squealing something fierce.

Wheel removal


I removed the wheel. Boy are loaded tires, plus wheel weights heavy.

Part number


It was awesome to see some original part numbers still painted on in rather great condition.

All apart. This was rather easy to get to this point. The dowel pins holding the final to the rear put up minimal fight.

Source of noise


Here we have the source of the noise. I don’t know why it is wearing like this. But the drum looks good so I ordered up the parts required. While I’m in here I have to replace the axle bearing in the final. It is pretty sloppy. Hopefully my parts arrive soon as the grass is getting tall.

Hi,
The Cub looks good in your pics.

Before splitting a Cub, you should put wooden wedges at the front axle pivot. A Cub is heavier on the left side, and they can tip over when removing large parts from the rear of them, or splitting them.
Below is a pic of the wedges, you will need to make them. Drive them in tight with a hammer, and check them some during the work and be sure they don't come loose.
They should be tight on the top and bottom sides. Cut off the small end some if they hit at the small end.
I can't see in your pics if you have wedges there.
It's good that you have the left rear wheel and tire there.

I think they have said on here, if the metal part of the brake band rubs on the brake drum, bend the band slightly so it doesn't rub.
The lining looks about down to the rivets in your pic, I can't see if they all are down to the rivets or not.
TM Tractor has brake and final drive parts. :)

I didn’t give the wedges a thought at the time. Probably should though. I’d rather not have to figure out picking it up.

The rivets you see in the picture is rubbing the drum. But all the others have about a 1/8 of lining left before touching. However the lining is looking raggedy so it’s better off to be replace. All the parts are coming from TM. :wink:

It is good to replace the oil seals on the upper shaft when you remove a final drive.

There is an oil seal behind the brake drum, in the final drive.
The shaft the brake drum is on slides out the hole where the cover with the 4 bolts is, after removing the brake drum, and the brake drum key.

There is another oil seal in the transmission. You can use a light and look in the the extension, and see if the seal is leaking.
It is some work to replace it, you have to remove the seat, the battery box, and loosen the platform, so the rear of it will raise up some. I think the pedals can stay there, the rear will lift some.
Then remove the right side extension.

TM Tractor has new seals. The seals are 2 different sizes. :)

Well. Finally got a little dry weather to put this back together. Tested it out digging a little ditch to drain my swamp of a yard.

Next up is a carb rebuild. It leaks and lacks a bit of power.

Hi,
Good that you got the Cub together.

If the Cub doesn't have good power, it may need a complete tune up. Ignition points, condenser, distributor cap, rotor, spark plug wires, spark plugs. The points get burned from use.
It's important the points have flat, smooth surfaces.
The points need to have the right gap.
I would check the timing, it's important the timing be right. The Cub service manual says use a timing light with a Battery Ignition unit.
If the timing is off, it can have less power than it should.

The manuals you have should show how to work on the points.

A compression test would be good to do, then you know if the compression is good.
The Cub service manual says a Cub engine has 120 lbs of compression, that is probably for a new engine.
Some less is ok, 90 lbs or above.
Open the throttle fully when doing a compression test, so the engine can get air for the test.
Remove all 4 spark plugs, so they are out of the engine at the same time.
Use the starter for the test.
Charge the battery fully for the test.
I write down the results, so I have a record.

TM Tractor at the bottom of the page has new points and condenser, and other ignition parts.

I noticed in your pic it looks like the parts on the Fast Hitch lift rod are assembled wrong.
The stop collar goes ahead of the other parts. Then you can set it where you want.
If you are backing up with a trailer, that has 2 wheels and is balanced, the hitch can raise up if the collar is not back against the other part to the rear of it.

Below is a pic of the rod and collar, showing where it should be, ahead of the other parts.
The collar is set in the pic for plowing, the plow should float up and down, as it needs to.
The rod can bend if you try to force implements into the ground.

Yours may have a different part on the lift rod. There is a spacer on the rod, ahead of the nut, it has no bolt in it. I can't see yours too good in the pic.
Below is a page from the 1955 Cub operator's manual showing the Fast Hitch and lift rod. :)

It is assembled wrong haha. Still got some going through it to do. I need to find some sort of bushing for the lift rod as the eyelet is very loose.

So today I did a bit of investigation. The tractor would run and drive but once you put a load on there was nothing. Here are some pictures.

The wire to the coil is dust now. Ordered up the tune up parts. It’ll be nice to see how it runs after this.

Hi,
I measured the spacer on the lift rod on my Cub, it is 1 1/2" long.
It is a good fit on the rod, but slides freely on the rod.

If I'm reading this post correctly, what you are missing is the trunnion bushing.

OK. Not the part I was thinking of. Since the hole is worn oblong, a bushing may or may not help. In similar situations, I have had the hole welded up and redrilled to the correct size. You may also find some wear on the rock shaft pin.

I was thinking of welding it and re drilling. However there are remains of some sort of bushing I do believe. Maybe I can take some measurements and find something online.

Not sure if you already saw this HOW TO, but maybe this will help:
